Description

  The present invention relates to a CSG kneading apparatus that is installed at a site and can efficiently knead high-quality CSG.

  It is important that a CSG kneading apparatus for adding and kneading cement and water to a locally generated material efficiently kneads a large amount of locally generated material into a CSG. Moreover, CSG is used for concrete structures, such as a dam, with non-flowable concrete, such as RCD. CSG is a non-flowable concrete made by mixing cement with local materials generated by excavating a dam construction site, and has the advantage that it can be used effectively without discarding the local materials. RCD is an abbreviation for roller-compacted dam. It is a mixture of selected aggregate and cement.

Since non-flowable concrete such as CSG and RCD and ready-mixed concrete are used in concrete structures such as dams, the amount used is extremely large. For this reason, the apparatus which knead | mixes CSG, RCD, and ready-mixed concrete is requested | required of very big processing capacity. CSG can effectively use locally generated materials, but in many cases, it is difficult to construct a concrete structure with only CSG. For example, the interior of a concrete structure such as a dam constructed with ready-mixed concrete is constructed with CSG. When building with CSG and ready-mixed concrete, there are times when CSG is supplied to the site and ready-mixed concrete is supplied. For example, the concrete structure is constructed by switching between morning and afternoon, supplying CSG and ready-mixed concrete, supplying CSG one day, and supplying ready-made concrete the next day. At this time, in a construction site that requires CSG and ready-mixed concrete, a plant for kneading ready-mixed concrete and a dedicated plant for kneading CSG are installed at the work site. A CSG production plant has been developed (see Patent Document 1).
Japanese Patent Laid-Open No. 11-60314

  This publication describes a CSG manufacturing plant in which cement and water are added to a locally generated material and kneaded. At construction sites such as dams, CSG and ready-mixed concrete are installed as two very large plants consisting of a plant that produces CSG from locally generated materials and a ready-mixed concrete manufacturing plant as described in this publication. Need to supply. CSG is made by adding cement to the locally generated material and kneaded, and ready-mixed concrete is made by adding cement to the aggregate and kneaded, but the kneaded state is considered to be considerably different. CSG is simply kneaded by adding cement to the locally generated material, while ready-mixed concrete is required to be sufficiently kneaded by adding cement and aggregate. In this way, CSG and ready-mixed concrete with considerably different physical properties are manufactured by dedicated equipment, but this kind of plant used for dam construction is extremely large, so two of them are installed. In addition, the equipment cost is extremely high. Also, since CSG and ready-mixed concrete are kneaded in separate dedicated plants, the equipment for transporting CSG and ready-mixed concrete from each plant to the construction site becomes complicated, and there is a disadvantage that it cannot be transferred efficiently with simple equipment. is there.

  Furthermore, the apparatus described in the above publication transports the locally generated material to a continuous mixer with a belt conveyor and kneads the continuous generated material into a CSG, so that the locally generated material, cement and water are in a certain ratio. There is a drawback that it is difficult to control and knead uniformly. This is because it is difficult to supply all the locally generated materials, cement and water to a continuous mixer at a fixed ratio. Moreover, since this apparatus cannot supply locally generated material at once by a backhoe or the like, it has a drawback that it is difficult to supply a large amount of locally generated material easily and efficiently. In addition, when the supply amount of locally generated material becomes non-uniform, the manufactured CSG is also non-uniformly kneaded, which makes it impossible to obtain a high-quality CSG.

The present invention has been developed for the purpose of solving such drawbacks. An object of the present invention is to provide a CSG kneading apparatus capable of producing a high-quality CSG by uniformly kneading a locally generated material and cement while supplying the locally generated material to a mixer easily and easily by a backhoe.

A water supply unit 5 that stores the water supply ratio with respect to the weight of the locally generated material and supplies the stored supply ratio of water to the mixer 1 is provided. In this kneading apparatus, when a predetermined amount of locally generated material is supplied to the mixer 1 by the backhoe 20, the weight of the supplied locally generated material is detected by the weigh scale 3. Further, in the kneading apparatus, the cement supplier 4 supplies cement at a specific supply ratio to the detected weight of the locally generated material, and the water supplier 5 supplies a specific supply ratio with respect to the weight of the locally generated material. Then, the mixer 1 kneads the supplied locally generated material, cement and water.

  Furthermore, the kneading apparatus of the present invention can knead by switching between CSG and ready-mixed concrete. In this kneading apparatus, the cement supply device 4 stores the cement supply ratio with respect to the aggregate weight, and the water supply device 5 stores the water supply ratio with respect to the aggregate weight. When a predetermined amount of aggregate is supplied to the mixer 1, this kneading apparatus detects the weight of the supplied aggregate with a weigh scale 3, and supplies cement at a specific supply ratio to the detected weight of the aggregate. The vessel 4 supplies cement, and further, the water supply device 5 supplies water at a specific supply ratio with respect to the weight of the aggregate, and the supplied aggregate, cement, and water are kneaded by the mixer 1. Ready-mixed concrete.

  In the CSG kneading apparatus of the present invention, a hopper 2 for supplying locally generated material supplied from the backhoe 20 to the mixer 1 can be disposed at the opening of the mixer 1.

The mixer 1 can be disposed above the loading platform 22 of the truck 21 that enters the loading / unloading space 8 and the CSG discharged from the mixer 1 can be supplied to the loading platform 22 of the truck 21. In this kneading apparatus, the mixer 1 is provided with a discharge port having an opening / closing door at the bottom, and the CSG can be dropped onto the loading platform 22 of the truck 21 by opening the opening / closing door.

  In the CSG kneading apparatus of the present invention, the weigh scale 3 includes a load cell, and the mixer 1 can be attached to the frame 6 through the load cell. The load cell can connect the four corners of the mixer 1 to the frame 6.

  In the CSG kneading apparatus of the present invention, the cement feeder 4 includes a silo 14 for storing cement, and the cement stored in the silo 14 can be supplied to the mixer 1. Furthermore, the CSG kneading apparatus of the present invention includes a measuring mechanism for measuring the amount of cement supplied to the mixer 1 by the cement supplier 4, and supplies the cement measured by the measuring mechanism to the mixer 1. it can. Furthermore, the CSG kneading apparatus of the present invention can measure the amount of cement supplied to the mixer 1 with a weigh scale 3 that measures the weight of the locally generated material.

  The CSG kneading apparatus of the present invention includes a flow meter 18 that measures the amount of water supplied to the mixer 1 by the water supply device 5, and can supply water measured by the flow meter 18 to the mixer 1. Furthermore, the CSG kneading apparatus of the present invention can measure the amount of water supplied to the mixer 1 with a weigh scale 3 that measures the weight of the locally generated material.

  The CSG kneading apparatus of the present invention is provided with a timer for storing the CSG kneading time and ready-mixed kneading time in the mixer 1, and when the locally generated material, cement and water are supplied to the mixer 1, When the kneading time is kneaded to make CSG, and the aggregate, cement and water are supplied to the mixer 1, the ready-mixed concrete can be kneaded to make ready-mixed concrete. The mixing time of ready-mixed concrete stored in the timer can be 40 to 120 seconds. The CSG kneading time stored in the timer can be 10 to 60 seconds.

  The CSG kneading apparatus of the present invention is capable of producing a high-quality CSG by uniformly kneading the locally generated material and cement while supplying the locally generated material to the mixer easily and easily by a backhoe. There is. The CSG kneading apparatus of the present invention is equipped with a weigh scale that measures the weight of the locally generated material supplied to the mixer, and the cement feeder has a specific supply ratio with respect to the weight of the locally generated material. This is because the cement is supplied to the mixer, and the water supply unit supplies water at a specific supply ratio with respect to the weight of the locally generated material, and the locally generated material, cement and water are kneaded by the mixer. . The kneading apparatus of the present invention does not supply the locally generated material, which has been weighed in advance, to the mixer, but measures the weight of the locally generated material supplied to the mixer with a weigh scale, and measures the locally generated material. Cement and water are supplied at a specific supply ratio with respect to the weight of Therefore, using a heavy machine that does not have a weighing function such as a backhoe, the weight of the locally generated material can be accurately measured while supplying the locally generated material to the mixer simply and easily and efficiently. The generating material, cement, and water can be uniformly supplied at an accurate ratio and kneaded. In particular, it has the advantage that it can manufacture high-quality CSG while easily and efficiently supplying a large amount of locally generated materials at once at a backhoe.

  Further, in the kneading apparatus according to claim 2 of the present invention, the cement feeder stores the cement supply ratio with respect to the aggregate weight, and the water supplier stores the water supply ratio with respect to the aggregate weight. Therefore, it is possible to knead the ready-mixed concrete by supplying cement and water at a specific supply ratio with respect to the weight of the supplied aggregate. This kneading apparatus has an advantage that both CSG and ready-mixed concrete can be efficiently adjusted and supplied by one apparatus.

  Embodiments of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify a CSG kneading apparatus for embodying the technical idea of the present invention, and the present invention does not specify the CSG kneading apparatus as follows.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The CSG kneading apparatus shown in FIGS. 1 to 3 includes a mixer 1 having a supply portion for locally generated material opened upward, and a local portion supplied from a backhoe 20 with a lower end connected to the opening portion of the mixer 1. A hopper 2 for supplying the generated material to the mixer 1, a weight meter 3 provided in the mixer 1 for detecting the weight of the locally generated material supplied to the mixer 1, and the weight of the locally generated material measured by the weight meter 3 Storing the cement supply ratio to the cement, storing the cement supply 4 for supplying the cement with the stored supply ratio to the mixer 1, storing the water supply ratio with respect to the weight of the locally generated material measured by the weighing scale 3, and A water supply unit 5 is provided for supplying the mixer 1 with water in a supply ratio to be stored.

  The CSG kneading apparatus shown in these drawings has a mixer 1 mounted on a frame 6. The frame 6 has the mixer 1 mounted on a plurality of columns 6A. The frame 6 shown in the figure has four support posts 6A arranged at the four corners, the deck plate 6B is fixed horizontally on the support posts 6A, and the platform 7 is placed on the deck plate 6B via the weighing scale 3. The mixer 1 is fixed on the platform 7. Further, as shown by the chain line in the figure, the frame 6 in the figure is provided with an entrance / exit space 8 through which the truck 21 for transporting the CSG kneaded by the mixer 1 enters between the columns 6A. In this frame 6, the mixer 1 is disposed above the loading platform 22 of the truck 21 that enters the entrance / exit space 8, so that CSG discharged from the mixer 1 can be supplied to the loading platform 22 of the truck 21.

  The frame 6 is disposed at a height located above the loading platform 22 so that the deck plate 6B does not come into contact with the loading platform 22 of the truck 21 entering below. The deck plate 6 </ b> B has the pillars 6 </ b> A fixed at the four corners so as to have a horizontal posture. The frame 6 in the figure is provided with a walking section 9 around which the operator can walk around the mixer 1. Therefore, the deck plate 6 </ b> B has a larger outer shape than the mixer 1 and connects the ladder 10. This frame 6 can efficiently and easily check the mixer 1.

  The mixer 1 switches between CSG and ready-mixed concrete and kneads one of them. That is, CSG is kneaded in some cases, and ready-mixed concrete is kneaded in other cases. The mixer 1 is a batch-type mixer in which cement and water are kneaded with supplied locally generated materials and aggregates. The mixer 1 can be of any mechanism that is already used or will be developed. The batch-type mixer shown in the figure includes a container 11 having an opening at the top, and an agitation blade 12 for agitating cement and water to the locally generated material and aggregate inside the container 11. The blade 12 is rotated by a rotation mechanism 13 such as a motor. However, the mixer can stir the contents by rotating the container with a rotating mechanism, or can stir by rotating both the container and the stirring blade.

  The mixer 1 is provided with a discharge port at the bottom having an open / close door (not shown) for discharging the kneaded CSG and ready-mixed concrete. The open / close door closes the discharge port when cement and water are mixed into the locally generated material and aggregate. The mixer 1 opens the door and discharges the kneaded CSG and ready-mixed concrete from the outlet.

  Although not shown, the mixer 1 has a built-in timer for storing the CSG kneading time and the ready-mixed kneading time. This timer stores the kneading time of CSG as a time shorter than the kneading time of ready-mixed concrete. For example, the CSG kneading time is shortened to 10 to 70%, preferably 30 to 70%, more preferably 40 to 60%, and most preferably about 50%, where the green concrete kneading time is 100. The timer stores, for example, a CSG kneading time of 10 to 60 seconds, preferably 30 seconds. Moreover, the kneading time of ready-mixed concrete is stored as 40 to 120 seconds, preferably 60 seconds.

  The hopper 2 is disposed in the opening of the mixer 1. The hopper 2 has a lower end connected to the mixer 1 so as to increase the opening area toward the upper end. The hopper 2 is fixed to the container 11 of the mixer 1. The hopper 2 supplies the locally generated material supplied from the backhoe 20 to the mixer 1. The mixer 1 in which the hopper 2 is connected to the opening can be efficiently and simply supplied by the backhoe 20 so that the locally generated material is not taken outside the mixer 1. However, it is not always necessary to connect a hopper to the mixer. It is also possible to enlarge the mixer opening and feed the locally generated material directly into the mixer opening without a hopper with a backhoe.

  The weigh scale 3 measures the weight of locally generated materials and aggregates supplied to the mixer 1. The weigh scale 3 measures the weight of the entire mixer, and accurately measures the locally generated material supplied to the mixer 1 through the weight of the entire platform. The weigh scale 3 measures the empty weight without supplying the locally generated material to the mixer 1, and then measures the filling weight while supplying the locally generated material. The weigh scale 3 can measure the weight of the locally generated material by subtracting the empty weight from the filling weight. In the illustrated mounting, the four corners of the platform 7 are connected to the deck plate 6B via the weighing scale 3. The weighing scale 3 is disposed between the platform 7 and the deck plate 6B, that is, on the deck plate 6B and below the platform 7, and weighs the entire platform. The weight scale 3 is a load cell. However, the weighing scale can be anything other than a load cell and capable of weighing. The apparatus for measuring the weight with the plurality of weighing scales 3 adds the measured values of all the weighing scales 3 and measures the weight of the entire platform. The structure in which the platform 7 is connected to the deck plate 6B via the weight meter 3 made of a load cell can be easily constructed because the platform 7 can be connected to the deck plate 6B via the load cell. However, although not shown, the CSG kneading apparatus can measure the weight of the locally generated material supplied to the mixer with one weighing scale. In this apparatus, the platform is connected to the deck plate so that the platform can be moved up and down, and the platform that moves up and down is connected to the weighing scale via a link mechanism.

  The cement feeder 4 supplies a specific amount of cement to the mixer 1. The cement feeder 4 stores the cement supply ratio with respect to the weight of the locally generated material. The cement feeder 4 stores the amount of cement with respect to the locally generated material by weight or volume. When the weight of the locally generated material supplied to the mixer 1 is detected by the weigh scale 3, the cement feeder 4 controls the supply amount so that a specific supply ratio is obtained with respect to the detected weight of the locally generated material. Then, the cement is supplied to the mixer 1. The cement feeder 4 storing the supply ratio in terms of cement weight supplies the mixer 1 with 3 to 10 wt% of cement relative to the weight of the locally generated material when kneading the CSG. Further, when kneading the ready-mixed concrete, 5 to 20 wt% of cement is supplied to the mixer 1 with respect to the aggregate weight.

  The illustrated cement feeder 4 includes a silo 14 that is disposed adjacent to the frame 6 and temporarily stores cement, and a screw conveyor 15 that supplies the cement of the silo 14 to the mixer 1. The cement feeder 4 measures the amount of cement having a specific supply ratio with respect to the locally generated material by a measuring mechanism (not shown) and supplies it to the mixer 1. The measuring mechanism measures the weight of cement or measures the amount of cement by measuring the volume. The screw conveyor 15 can control the amount of cement supplied by operating time. Therefore, a timer for controlling the operation time of the screw conveyor 15 can be used as a measuring mechanism. Moreover, the rotary feeder which measures the volume of cement can be connected to the screw conveyor 15, and a rotary feeder can also be used as a measuring mechanism. The cement feeder 4 is not necessarily provided with a metering mechanism. This is because the amount of cement supplied to the mixer 1 can be measured by a weigh scale 3 that measures the weight of the locally generated material. A cement feeder without a measuring mechanism supplies cement to the mixer while measuring the amount of cement with a weigh scale.

  The water supplier 5 supplies a specific amount of water to the mixer 1. The water supply device 5 stores the water supply ratio with respect to the weight of the locally generated material. The water supply device 5 stores the amount of water for the locally generated material in terms of volume or weight. When the weight of the locally generated material supplied to the mixer 1 is detected by the weigh scale 3, the water supply device 5 controls the supply amount so that a specific supply ratio is obtained with respect to the detected weight of the locally generated material. Then, water is supplied to the mixer 1. The water supply device 5 storing the supply ratio by volume or weight supplies the mixer 1 with a water amount of 5 to 10 wt% with respect to the weight of the locally generated material when kneading the CSG. Moreover, when knead | mixing fresh concrete, the water used as 5-15 wt% with respect to aggregate weight is supplied to the mixer 1. FIG.

  The water supply 5 shown in the figure is disposed adjacent to the frame 6, a water tank 16 for temporarily storing water, a pump 17 for supplying water from the water tank 16 to the mixer 1, and a pump 17 for supplying water. A flow meter 18 for detecting the flow rate is provided. The water supply device 5 measures the amount of water with a specific supply ratio with respect to the locally generated material with the flow meter 18 and supplies the water to the mixer 1. The water supplier 5 can also control the amount of water supplied by the operation time of the pump 17. In addition, an on-off valve (not shown) is connected to the discharge side of the pump 17, and the amount of water supplied to the mixer 1 can be controlled by the time for opening the on-off valve while the pump 17 is in operation. Therefore, the amount of water can be measured and supplied to the mixer 1 by a timer that controls the operation time of the pump 17 or the opening time of the on-off valve. Moreover, the water supply device does not necessarily need to be provided with a flow meter. This is because the amount of water supplied to the mixer can be measured with a weigh scale that measures the weight of the locally generated material. A water supply device without a flow meter supplies water to the mixer while measuring the amount of water with a weigh scale.

The above CSG kneading apparatus kneads CSG and knead ready-mixed concrete as follows.
[Method of kneading CSG]
(1) The backhoe 20 supplies the locally generated material from the hopper 2 to the empty mixer 1. The locally generated material is not measured and supplied to the mixer 1. For this reason, the locally generated material supplied from the backhoe 20 is not a constant weight.
(2) The weighing scale 3 measures the weight of the locally generated material supplied to the mixer 1. The weighing scale 3 measures the weight of the locally generated material by subtracting the weight of the empty mixer, that is, the state of not supplying the locally generated material, that is, the weight of the empty mixer from the weight of the state where the locally generated material is supplied.
(3) The cement supplier 4 supplies cement to the mixer 1 at a supply ratio corresponding to the weight of the locally generated material. At this time, the mixer 1 is rotated or not rotated. When cement is supplied while rotating the mixer 1, the supplied cement can be supplied while mixing with the locally generated material.
(4) The water supply device 5 supplies water to the mixer 1 at a supply ratio corresponding to the weight of the locally generated material. Also at this time, the mixer 1 is rotated or not rotated. When water is supplied while rotating the mixer 1, the supplied water can be supplied while mixing with the locally generated material.
Although cement and water are supplied to the locally generated material to the mixer 1, the cement supplier 4 and the water supplier 5 can supply cement and water to the mixer 1 together.
(5) The mixer 1 is operated and the locally generated material, cement and water are mixed to form CSG.
(6) Open the open / close door provided at the bottom of the mixer 1 in a state where the truck 21 is inserted below the mixer 1, and discharge the CSG from the outlet to the loading platform 22 of the truck 21.

The time for discharging the kneaded CSG is 20 seconds, and the total time for one cycle is 110 seconds.

[Method of kneading ready-mixed concrete]
(1) Aggregate is supplied from the hopper 2 to the empty mixer 1. The aggregate is supplied to the mixer 1 without being measured. The aggregate is supplied to the mixer 1 by the backhoe 20, or is supplied to the mixer 1 by a belt conveyor (not shown).
(2) The weigh scale 3 measures the weight of the aggregate supplied to the mixer 1. The weigh scale 3 measures the weight of the aggregate by subtracting the weight of the state in which no aggregate is supplied, that is, the weight of the empty mixer 1 from the weight in the state in which the aggregate is supplied. However, the aggregate can be measured and supplied to the mixer 1. When the aggregate is fed to the mixer 1, it is not necessary to weigh the aggregate with the weigh scale 3 in this step. Aggregate supplied by measurement is supplied to the mixer 1 as a set weight.
(3) The cement supplier 4 supplies cement to the mixer 1 at a supply ratio corresponding to the weight of the aggregate. At this time, the mixer 1 is rotated or not rotated. When cement is supplied while rotating the mixer 1, the supplied cement can be supplied while being mixed with the aggregate.
(4) The water supply device 5 supplies water to the mixer 1 at a supply ratio corresponding to the weight of the aggregate. Also at this time, the mixer 1 is rotated or not rotated. If water is supplied while rotating the mixer 1, the supplied water can be supplied while being mixed with the aggregate.
The mixer 1 is supplied with cement and water to the aggregate, but the cement supplier 4 and the water supplier 5 can supply cement and water to the mixer 1 together.
(5) The mixer 1 is operated to knead aggregate, cement and water to make ready-mixed concrete.
(6) Open the open / close door provided at the bottom of the mixer 1 with the truck 21 intruded below the mixer 1, and discharge the ready-mixed concrete from the outlet to the loading platform 22 of the truck 21.

  In the above process, the time required for supplying the aggregate, cement and water to the mixer 1 of (1) to (4) is 60 seconds, and the time for the mixer 1 to knead in (5) is 60 seconds. The time for discharging the kneaded CSG is 20 seconds, and the total time for one cycle is 140 seconds.
